The male peacock is the classic example of how under sexual selection males have evolved spectacular gaudy adornments to impress choosy females.

Evolution of extravagant courtship displays and coloration signalling a male’s sexiness to seduce females is ubiquitous throughout the animal kingdom and is by no means restricted to birds. An epitome of sexual selection in favouring astounding male courtship displays and appearance occurs in peacock spiders. Whilst measuring a mere 5mm, like their namesakes, male peacock spiders are arguably even more outrageous when it comes to bright appearances and behaviours to entice the comparatively drab brown (yet well camouflaged) female peacock spiders to mate with them.
